Our invention relates to machines for burnishing the heels of boots and shoes.

It consists in various arrangements of devices for finishing the different portions of the heel, and it contains also a set of devices for jacking or holding the shoe while the operation is being performed.

A is the base of the machine. I) Z) are two curved arms or supports rising from the base and carrying the shaft 0, which has the pulley d, where power is applied. The shaft 0 carries the disk 6 at one end, set in a circular recess in the curved arm I). A little out of the center of this disk is the stud f, projecting a short distance. This stud is intended to enter the hole 9 in the link h. The link It has also the hole z to receive a stud inthe plate 7.1. This plate 70 has a pivot which enters the hole on in the arm b. It is there held by the screwbolt n and the washer 0. The screw-bolt or enters a screw-socket in the end of the pivot, and thus holds it by means of the washer 0. WVc

are now enabled to see that when the shaft 0 is made to revolve a vibratory motion is imparted to the plate It. The purpose of this will now be explained. This plate It has a channel, 1", 011 its outer side, which is covered by the covering-plate s. Into this channel is fitted the arm twith a shoulder, a, on it, a part, 12, and a spiral spring, to. On the outer end of this armt are set the burnishing devices, which, all taken together, we will designate by B. We will, as the description progresses, designate the parts by other letters. This entire device or set of devices, it will now be understood, has a rapid vibratory motion on the arm t. The part :0 is to give a polishor burnish to the whole edge of the heel, and may be curved and shaped so as to fit heels of any desirable shape. It exhibits corrugations drawn diagonally across its surface. These are rounded in form, as seen in Fig. 4. The object of the corrugations is to give a polish in which the blacking is worked into the leather, which a plain surface would not do. The diagonal direction gives a better friction on the heel. This part of the burnisher is used after the part y, which we will now describe. The part 3/ is to give a smooth or finished edge to the top lift of the heel. This is difficult to do, and in many machines and in hand-work the edge of this lift is often left ragged and irregular. lVith the use of a mere plain surface it would require much more time. The edge of the top lift is pressed with proper firmness into the angle z,a1.d by the combined action of the corrugated surface y and the smooth surface (1, at right angles thereto, a smooth polished edge is given to the top lift. It will be seen that the part as, near the smooth portion d,has a somewhat more abrupt curve than at other portions. The object of" this is to prevent the smoothed and finished edge of the top lift from coming in contact with the burnisher at all after it has once been finished on the parts just above describedto wit, 1 and z. The part :0 is where the operation is It is com- The ridge No. 1 is ICO to go over the edge of the lift or in between it and the upper. Ridge 2 is the one that makes the marking or beading on the edge of the lift. Ridge 3 isa gage to prevent ridge 2fro1n entering into the leather too deeply. Thus the usual figuring or beading is impressed on the heel at this point, and the edge of the lift made smooth.

The arm t, as has been shown, has the spiral spring, one end bearing against the shoulder u, and the other against the end of the channel 1". This is to relieve the pressure on the heel of the boot or shoe ifthe operator should press too hard.

Rising from the base A is the standard 0.

Over this standard fits a head, f, through which slides the horizontal stock 9. The stock 9 carries the devices for jacking or holding the boot or shoe while the heel is being finished. First, is the horizontal joint i, admitting of the boot or shoe being so turned as to aid in presenting all parts of the heel to the burnishing device; second, is the jack or device forholding the boot directly. This is done by a split eXpanding-pin,j, which enters the hole in the top of the last. The pin is inserted when the two parts are closed. WVhen once inserted, the parts are expanded, and thus the pin is held firmly and securely in the hole in the last. The boot or shoe is on the last. It is thus presented to the burnishing devices for finishing the heel.

The split eXpanding-pinj is operated in this manner. The two parts Z m of the split eX- panding-pin are connected with two curved arms, a o. A straight part, 19, of these two arms passes through a head, q. The straight part p is united in the manner shown in Fig. 5, where one-half of the straight part has two jaws and the other a tongue to fit between them. This is illustrated in the detail, Fig. 7. Apin passes through the head q and the tongue and jaws, and thus furnishes a pivot for the movement of the two parts of the split expandingpin.

8 is a bifurcated lever pivoted to the curved arm n.

t is a lever pivoted at v in the bifurcations of the lever s. The arm 0 also passes in through the bifurcations of the lever s.

a is a curved rack on the curved arm it, into the teeth of which fits the end of the lever i like a pawl. A spring, 10, keeps the end of the lever s pressed into the teeth of the rack to, in order to hold the two levers at any desired point. The pivot 1/ also carries the two rollers 90, and these come in contact with the face of the curved arm 0, and by pressing it upwardly open the two parts of the split expanding-pin. (See Fig. 5.) By moving the bifurcated lever 5 forward the curved arm 0 is brought up nearer to the arm n, and thus the two parts of the split expanding-pin are forced apart. Thus when the pin is entered into the hole in a last, which last is in a shoe, it (the pin) can be made to fit very tightly and hold itself very firmly in said hole.

The split expanding-pin with its accompanying devices is capable of a complete rotation in a vertical plane. This is accomplished by the pin a socket b groove (1 and screw 0". screw 0 enters the groove d Thus the entire portions of the device, including the friction-joint, the split expanding-pin, the curved arms, and the two levers, can revolve as described. This motion is produced in order to give that complete revolution to the shoe which is necessary in order to present all parts of the heel all around to the action of the burnishing devices before described. Some lasts have the holes made in them at an inclination or angle. If there were no way to correct the effectjof this, the shoe could not be properly presented to the burnisher. The shoe must always be so presented, straight or level, and without any inclination. To insure this, a friction-joint is made at 3 which admits of an inclination being given to the split expanding-pin to correct the inclination there may be in the hole of the last. The stock 9 is made to slide in the head f. This movement may become desirable and necessary from the size of the shoes, which may require the stock to be pushed back or forward somewhat while the heel is being operated upon.
